A metallic cube of side 15 cm moving along y-axis at a uniform velocity of 2 m s -1 . In a region of uniform magnetic field of magnitude 0.5T directed along z-axis. In equilibrium the potential difference between the faces of higher and lower potential developed because of the motion through the field will be mV.
Text Solution
Verified by ExpertsThe correct answer is:
150
(150)
Using the equation
qE = qvB
E = vB
Using the relation 
V = Ed
F = vBd
= 0.15 V = 150 mV
